Abullet of mass m = 0.029 kg is fired with a speed of vi = 94.00 m/s and hits a block of mass m = 2.52 kg supported by two massless strings. the bullet emerges from the right side of the block with a speed of vf = 47.00 m/s. find the height to which the block rises.

Awave has a wavelength of 7 mm and a frequency of 19 hertz. what is its speed?

The average atmospheric pressure on earth is approximated as a function of altitude by the relation patm = 101.325 (1 − 0.02256z)5.256, where patm is the atmospheric pressure in kpa, and z is the altitude in km with z = 0 at sea level. determine the approximate atmospheric pressures at atlanta (z = 306 m), denver (z = 1610 m), mexico city (z = 2309 m), and the top of mount everest (z = 8848 m).
